Read our privacy policyThe Airrex AHSC-18R is a 16,800 BTU cooling and 18,500 BTU heating portable heat pump designed to provide supplemental heating and cooling for commercial, industrial, and temporary work environments. Combining high-capacity heating and cooling performance with reversible heat pump technology, this self-contained heating and cooling system provides year-round temperature control while offering flexible placement and easy relocation between work areas. Designed for spaces up to approximately 600 square feet under suitable conditions, the AHSC-18R offers portable climate control without requiring a permanent HVAC installation.
The Airrex AHSC-18R provides 18,500 BTU of heating capacity to help maintain comfortable temperatures in suitable commercial and industrial environments. Its specified heating operating range is 46°F to 81°F, allowing the unit to provide supplemental warmth under appropriate ambient conditions. Reversible heat pump operation transfers heat into the conditioned space, offering an alternative to relying exclusively on conventional resistance heating. The unit is intended for supplemental heating applications where portable temperature control is needed.
The Airrex AHSC-18R provides 16,800 BTU of cooling capacity to help maintain comfortable temperatures during warmer conditions. Its specified cooling operating range is 59°F to 118°F. With an application coverage rating of up to approximately 600 square feet under suitable conditions, the unit is suited to localized cooling and supplemental room conditioning. Actual performance and coverage depend on heat load, ambient conditions, room configuration, ventilation, and exhaust installation. The system also provides dehumidification to help remove moisture from the air.
The Airrex AHSC-18R uses reversible heat pump technology with a four-way reversing valve to provide both heating and cooling from a single portable system. In cooling mode, the refrigeration cycle removes heat from the conditioned space. In heating mode, the cycle reverses to deliver warm air. The system also includes a dehumidification mode for moisture removal. The AHSC-18R uses R-454B refrigerant as specified in the current Airrex product lineup. This integrated approach provides seasonal temperature control without requiring separate portable heating and cooling equipment.
The Airrex AHSC-18R features an adjustable discharge louver that allows conditioned air to be directed upward, downward, left, or right. Its indoor centrifugal fan provides rated cooling airflow of 520 CFM at high speed and 440 CFM at low speed. The outdoor exhaust fan provides rated airflow of 870 CFM at high speed and 810 CFM at low speed. The 12-inch-diameter top exhaust connection supports heat rejection ducting, with a maximum equivalent exhaust duct length of 60 feet according to the manufacturer's specifications. Proper duct sizing and routing are important for maintaining airflow and system performance.
The self-contained portable design allows the Airrex AHSC-18R to be positioned where supplemental heating or cooling is needed without requiring a permanent HVAC installation. The cabinet measures approximately 22 inches wide, 25 inches deep, and 49 inches high, with a net weight of approximately 178 pounds. Four 4-inch swivel casters, including two locking casters, support movement and positioning on suitable surfaces. A 12-inch-diameter top exhaust connection accommodates appropriate heat-rejection ducting. The unit operates on a 115V, single-phase electrical supply. Installation must provide the required exhaust routing and clearances in accordance with the manufacturer's instructions.
The Airrex AHSC-18R incorporates an internal condensate tank with a 5-gallon capacity and an automatic full-tank shutoff function to help manage moisture generated during operation. A tank-position detector and automatic shutoff help prevent operation when the tank is improperly positioned or reaches its capacity limit. An optional compatible condensate pump is available for installations requiring automatic condensate removal and reduced manual tank-emptying requirements. Condensate management should follow the manufacturer's operating and maintenance instructions.
The Airrex AHSC-18R features digital controls for temperature adjustment and operating-mode selection. Available functions include heating, cooling, dehumidification, high and low fan speeds, and programmable timer settings. The unit operates on a 115V, single-phase, 60Hz electrical supply and is specified at 15.3 amps during cooling and 13.6 amps during heating. It uses a NEMA 5-20P plug with a 12 AWG, three-core power cord approximately 10 feet long. The manufacturer specifies a 20-amp circuit breaker. The electrical circuit, receptacle, and protective devices must be appropriate for the equipment and comply with applicable electrical codes. Built-in safety features include high- and low-pressure switches, compressor delay protection, compressor thermostat protection, and fan motor protection.
The Airrex AHSC-18R is designed for commercial and industrial environments that require flexible, localized heating and cooling. Potential applications include workshops, manufacturing facilities, maintenance areas, equipment rooms, server rooms, warehouses, temporary work areas, and other spaces requiring supplemental temperature control. Its 18,500 BTU heating and 16,800 BTU cooling capacities, directional airflow, and portable construction make it suitable for applications where permanent HVAC modifications are impractical or where conditioning requirements change seasonally. Confirm the space heat load, operating conditions, exhaust arrangements, electrical supply, and ventilation requirements before deployment.
The Airrex AHSC-18R features four 4-inch swivel casters, including two locking casters, to facilitate movement and positioning on suitable level surfaces. Its compact vertical cabinet helps the unit fit into a variety of commercial and industrial work areas. Locking casters help secure the equipment in place during operation. Before relocating the unit, follow the manufacturer's instructions for shutdown, condensate management, and safe movement.
The Airrex AHSC-18R features removable aluminum and stainless-steel mesh air filters for routine inspection and cleaning. Keeping filters clean helps maintain airflow and operating performance. Built-in safety devices include high- and low-pressure switches, a three-minute compressor delay timer, compressor thermostat protection, fan motor protection, automatic full-tank shutoff, and a tank-position detector. The condensate tank should be inspected and emptied as required unless a compatible condensate pump is installed. Perform cleaning, maintenance, and troubleshooting according to the manufacturer's operating manual.
The Airrex AHSC-18R is listed with a one-year warranty and a three-year compressor warranty. Warranty coverage, exclusions, registration requirements, and other applicable conditions are subject to the manufacturer's written warranty documentation. Review the applicable warranty terms before installation and operation.
